The Jeep Grand Cherokee WJ models, available in New Zealand from 1999 to 2005, blend luxury with robust off-road capabilities. Building on the renowned ZJ legacy, the WJ showcases refined design and impressive performance, making it an ideal choice for those who adventure as much as they commute. However, as these 4WD vehicles age, owners should be aware of common issues that may arise. This guide offers insights into WJ ownership tailored for Kiwis navigating these beloved vehicles.
Common issues include: 'Death Wobble' in the front end, linked to worn steering components and track bar. Overheating, often due to radiator or cooling fan issues. Leaking rear main seal (especially on the 4.0L). Electrical problems with window regulators and door locks. Transfer case issues (especially with the Selec-Trac system).
WOF inspections tend to focus on suspension components (ball joints, tie rod ends, sway bar links), brakes, and rust in the chassis. Ensure the headlights are properly aligned. Exhaust leaks are another common WOF failure point.
The WJ Grand Cherokee typically features either a 4.0L inline-six or a 4.7L V8 engine, providing robust power for off-road enthusiasts. Standard 4WD enhances its capability, while various transfer case options cater to different driving needs. As these vehicles age, attention should be given to drivetrain components, suspension systems, and rust prevention. Parts availability remains reasonable, but regular maintenance is vital.
Pay special attention to critical systems: for cooling, we recommend inspecting the water pump, thermostat, and radiator hoses around 150,000km to prevent overheating issues—this links to our Cooling category. Similarly, for braking performance, consider our Front and Rear Brake Services to ensure safety during your journeys. Lastly, keep an eye on filtration systems; regular replacements can enhance both engine performance and cabin air quality—don't forget to check out our Filtration category. Always request a full service history, particularly for transmission servicing, as this can spotlight potential issues before they escalate.
